Circuit diagram 6v emergency light circuit board.
The emergency lighting fixture is composed of a light source a light source driver a rectifier an inverter a battery pack a logo lamp housing something like that.
Referring to the circuit diagram we see that the circuit is actually very easy to understand let s evaluate it with the following points.
We carry emergency light circuit boards and exit sign circuit boards for a variety of brands.

Please suggest me the complete circuit diagram of automatic garden solar led light for.
I have tried this circuit but when i connect 6v smd led strip to the bd 140 collector terminal and ground the led was dimming very low as low as not glowing and i was measure the voltage respect to battery negative pole on emitter of bd 140 is shown 6 8 v but on collector is 4 3v.
The transformer bridge and the capacitor forms a standard power supply for the circuit.
And second part consists of relay and rechargeable battery which is used to lighten the leds during power failure.
The step down transformer and the diode bridge rectifier steps down and convert the high ac in the range of 110v or 230v voltage to low 12v dc voltage.
It has charging line too.
The diode d2 prevents the battery charge from flowing back it acts as a free wheeling diode too.
The transformer either you buy or make yourself.
Call us if you can t find the replacement you are looking for.

Even it shuts down when mains is on.
The circuit is basically made up of a single pnp.
This led emergency light circuit can be divided into two parts.
First part is used to drop down the 220v ac voltage into 8v regulated dc with the help of transformer and bridge rectifier.
